To celebrate the 40th anniversary of E.L. Konigsburgs 1967 win of the Newbery Medal and Newbery Honor--a feat never before repeated by any author--Aladdin Paperbacks is reissuing the entire Konigsburg oeuvre throughout 2007, including some long out-of-print titles, in luxurious, deluxe trade paperback editions.
2017 marks the fiftieth anniversary of the beloved classic From the Mixed-up files of Mrs. Basil E. Frankweiler.

When suburban Claudia Kincaid decides to run away, she knows she doesn't just want to run from somewhere she wants to run to somewhere--to a place that is comfortable, beautiful, and preferably elegant. She chooses the Metropolitan Museum of Art in New York City. Knowing that her younger brother, Jamie, has money and thus can help her with the serious cash flow problem she invites him along.

Once settled into the museum, Claudia and Jamie, find themselves caught up in the mystery of an angel statue that the museum purchased at an auction for a bargain price of $250. The statue is possibly an early work of the Renaissance master Michelangelo, and therefore worth millions. Is it? Or isn't it? Claudia is determined to find out. This quest leads Claudia to Mrs. Basil E. Frankweiler, the remarkable old woman who sold the statue and to some equally remarkable discoveries about herself.
